Abstract

A miniature circuit breaker (1) having a control unit (22) arranged to produce a trip signal to trigger a trip mechanism (20) into opening a pair of contacts (8,10) if it determines that an overcurrent condition occurs based on an output of a current sensor (23); an electric motor (25) operable to close the contacts via a contact closing mechanism (30a); a force transfer mechanism (70) arranged to transform a first trigger force into a second trigger force larger than the first trigger force, wherein the force transfer mechanism couples an electromechanical actuator (61) to a contact opening mechanism (30b) such that the second trigger force triggers the contact opening mechanism into opening the contacts; and/or a mechanical energy store (44, 46) arranged to accumulate mechanical energy from operation of the closing actuator (25) and subsequently to release accumulated mechanical energy to close the contacts.
